严寒地区典型城市既有非节能居住建筑节能改造效果分析

摘要

研究以严寒地区典型城市既有非节能居住建筑为对象,对2015-2016年、2016-2017年供暖季(节能改造前、后)换热站、二次输配管网及建筑本体三处节点进行供暖能耗实测.通过对比节能改造前、后各节点处的耗热量及相对应的标准,研究供热系统各个环节的实际与理论节能潜力,采用度日数及综合传热系数等方法对节能改造前、后的能耗加以修正;通过监测节能改造前、后建筑本体的室内温度,分析过量供热等因素对节能潜力的影响.基于对典型地区的节能效果分析,提出严寒地区典型城市既有居住建筑节能改造政策建议.%This study takes the non-energy saving residential buildings in the typical cities of severe cold area as the object,and analyzes the heating stations (before and after energy conservation) of the 2015-2016 and 2016-2017 heat transfer stations,secondary pipelines and construction bodies nodes for heating energy consumption measured.By comparing the actual and theoretical energy-saving potentials of all aspects of the heating system before and after the energy-saving transformation,the heat consumption at each node and the corresponding standard is used to study the energy consumption before and after the transformation Correction;by monitoring the energy efficiency before and after the construction of the indoor temperature,the analysis of excessive heating and other factors on the impact of energy saving potential.Based on the analysis of the energy efficiency of the typical areas and the analysis of the energy saving rate,this paper puts forward some suggestions on the energy saving reform of the existing residential buildings in the severe cities.
